| DWARF loader: |
| |
| - Read DW_TAG_LLVM_annotation tags, associating it with variables, functions, |
| types. So far this is only being used by the BTF encoder, but the pretty |
| printer should use this as well in a future release, printing these |
| attributes when available. |
| |
| - Initial support for DW_TAG_skeleton_unit, so far just suggest looking up a |
| matching .dwo file to be used instead. Automagically doing this is in the |
| plans for a future release. |
| |
| - Fix heap overflow when accessing variable specification. |
| |
| BTF encoder: |
| |
| - Support the new BTF type tag attribute, encoding DW_TAG_LLVM_annotation DWARF |
| tags as BTF_KIND_TYPE_TAG and BTF_KIND_DECL_TAG. |
| |
| This allows __attribute__((btf_type_tag("tag1"))) to be used for variables, |
| functions, typedefs, so that contextual information can be stored in BTF and |
| used by the kernel BPF verifier for more checks. |
| |
| The --skip_encoding_btf_type_tag option can be used to suppress this. |
| |
| - Fix handling of percpu symbols on s390. |
| |
| BTF loader: |
| |
| - Use cacheline size to infer alignment. |
| |
| btfdiff: |
| |
| - Now that the BTF loader infers struct member alingment, and as that is just |
| an heuristic, suppress printing the alignment when pretty printing from BTF |
| info like is done when printing from DWARF. |
| |
| pahole: |
| |
| - Add --skip_missing so that we don't stop when not finding one of the types passed |
| to -C. |
| |
| Pretty printer: |
| |
| - Fix __attribute__((__aligned__(N)) printing alignment for struct members. |
| |
| - Fix nested __attribute__(__aligned__(N)) struct printing order, so that |
| rebuilding from the printed source circles back to the original source code |
| alignment semantics. |
| |
| Build: |
| |
| - No need to download libbpf source when using the system library (libbpf-devel). |
| |
| - Make python optional |
